Just checked it, it exactly 21mm from the plate to under the bolt head like instructions said,

Try the Gates belt app, it might help. The frequency you need is in the set of directions for the kit.

Not all belts created equal, you have to find your sweet spot for the belt. It's going to take some time. Trial and error my friend.

They should get rid of the 21mm instruction in the manual. I installed mine that way and it was way too tight.

I really wished they put a spring loaded tensioner to rid of all the guess work.

Another issue I had was the pulley came installed on the blower unit but the bolts were semi tight (checked quickly by a small hex key). I was stupid and assumed they were torqued/loc-tite by KW. Pulley fell off 3000km later and luckly only broke the belt and scratched things up. They should have just left the pulley off or torqued them. Either way, KW has good customer service. They replaced my pulleys, belt and fluid for free.

How are you checking your belt tension now? The 60hz with the gates app?

sounds the same as when i got a seized tensioner pulley bearing. KW guys though were awesome and replaced it in no time.

That app never gave me any constant numbers. I gave up after it kept giving me random frequencies. I just kept adjusting it till I saw minimum belt slap. Still whines a tiny amount at idle and definitely audible at any speed above idle.

Okay, same here with the app giving inconsistent numbers. I couldn't figure out a way to correctly hold my phone and pluck the belt.

I think I'm going to have another look at my belt since I can't hear it at all right now. Figured it was just due to switching from smooth idlers to cogged ones.

DAN_BRZ · 05-20-2015, 04:56 PM

a whine at idle would mean the belt is too loose/tight? i have a whine at idle which gets louder at the rpms climb. ive been messing around with the belt the last few days trying to find the sweet spot.

Triumphrider · 05-20-2015, 04:57 PM

At idle I have no whine, but anything above idle you hear it

scionfr_s · 05-20-2015, 09:15 PM

Tension bolt?it didn't make any different even I'm losing it, tension pulley still spin
